# Planning a Replication Schedule

You can set up individual connection agreements to perform replication on a defined schedule. You must determine the most appropriate times for each replication process. A network with a large number of users may require more frequent replication than a smaller network. Also, some networks may require specific objects to be replicated more frequently than other objects.

These are some of the situations you must consider when planning a replication schedule:

- Will you be replicating more than 500 users or mailboxes? If so, you can improve performance by setting up multiple connection agreements to replicate different objects at different times.
- If you make daily changes to either directory and do not need the changes to appear in the other directory until the next day, you should schedule replication nightly.
- If there are times during the day when other replication occurs on either computer involved in the connection agreement, schedule the connection agreement around these times.
- If directory manipulation is commonly done at a specific time or times of the week, customize the replication to occur soon after the changes are made and only after the changes are made.

Use the connection agreement Schedule tab to establish a replication schedule for each connection agreement. For more information on setting up a replication schedule, see Set up a Replication Schedule.
